Q&A
How does Helmkes Landscape handle fence post rot and moss growth, common issues in King County's wet climate?
In King County, moisture and shade cause fence posts to rot and moss to grow on fence surfaces. We address these by using pressure-treated or cedar posts set in gravel for drainage, and we apply a protective sealant to the wood. For existing fences, we can replace rotted sections, power wash moss off surfaces, and apply a moss-resistant treatment to keep your fence looking clean and lasting longer.
Your deck repair or replacement process—do you handle everything from demolition to finishing?
Yes. Because we perform 99% of our work in-house, we manage every step of deck repair or replacement ourselves. This includes removing old decking, inspecting and replacing damaged joists, installing new deck boards, and applying stain or sealant. Our team works one project at a time, so your deck is completed without delays or subcontractors entering your property.
What makes your deck construction different from other contractors in King County?
We build one deck at a time, with the owner on-site daily. This ensures direct communication about design choices, material options (like cedar or composite), and any changes. Because we do the work ourselves, we can control quality and schedule—no waiting on subcontractors. Many of our King County customers come from referrals, which reflects our attention to detail and respect for their property.
